Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathe processing, in particular to an automatic waste chip cleaning device for a bearing numerically controlled lathe. Background Art

[0002] CNC lathe is a high-precision, high-efficiency automated machine tool. Equipped with a multi-station turret or a power turret, the machine tool processing performance can be more extensive. It can process straight cylinders, oblique cylinders, arcs, various threads, grooves, worms and other complex workpieces with good economic effects. It does not require human operation, and only needs to change the program that controls the machine tool movement to achieve the purpose of processing different parts.

[0003] The Chinese utility model patent with the authorization announcement number "CN216781179U" is specifically "a product outer surface drying device". The specific implementation method of its specification records that "when the two worms are driven to rotate by the driving component, the worm wheel and the worm are meshed and rotated, and the slider on the connecting frame is driven to slide on the guide rod. The brush connected to the lower end of the slider cleans the bottom of the protection box, so that the waste chips and cooling water fall into the long slot holes and enter the collection box through the collecting funnel. This device greatly reduces the labor intensity of workers and the waste chip recovery efficiency, and has a simple and effective structure; the waste chips left on the filter plate, when the filter plate rises to the highest point of the collection box, the piston rod of the hydraulic cylinder pushes the push plate to push the waste chips into the material box. The filter holes set on the material box can also play the role of cooling water filtering, and the material box is detachable, which can realize the recovery of waste chips";

[0004] The above-mentioned device uses a brush to move back and forth on the work surface to clean the metal scraps on the work surface. However, since some metal scraps are small in size, they are easily retained and entrained on the brush, causing the brush to fail to work normally, thereby reducing the cleaning effect of the brush. In addition, the brush is used to clean the metal scraps to the strip groove on the work surface for discharge. However, the strip groove has a small slot, and larger metal scraps cannot be discharged from the strip groove, further reducing the cleaning effect. More importantly, the device filters the metal scraps and wastewater through a filter plate. The metal scraps remaining on the filter plate are easily squeezed and crushed into fine particles when pushed to the push box by the piston rod, and fall from the mesh holes of the filter plate into the water storage tank, thereby reducing the separation effect of wastewater and metal scraps. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides an automatic waste chip cleaning device for a bearing CNC lathe, which can effectively solve the problems of poor cleaning effect and poor solid-water separation effect in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides an automatic cleaning device for waste chips of a bearing CNC lathe, comprising a workbench and a brush reciprocatingly mounted on the workbench surface, a filtering component comprising a metal mesh conveyor belt arranged at one end of the workbench and circling around, a wastewater recovery component comprising a return water hopper arranged on the inner ring wall of the metal mesh conveyor belt, and also comprising a water pump connected to a discharge port of the return water hopper, wherein the output end of the water pump is connected to a group of spray heads embedded and mounted on the inner wall of the workbench.

[0008] Furthermore, the workbench is designed to be inclined, and two servo motors are installed at one end. The output ends of the servo motors are installed with screws rotatably installed on the workbench surface, and the outer rod walls of the screws are threadedly fitted with nut seats.

[0009] Furthermore, a connecting seat is installed between the nut seats, and the brush is lifted and slidably inserted on the connecting seat, and the bottom is in contact with the workbench surface.

[0010] Furthermore, the filtering assembly includes two side plates arranged at the lower end of the workbench, two rotating rollers are rotatably installed between the two side plates, and the metal mesh conveyor belt is wrapped around the outer roller walls of the two rotating rollers.

[0011] Furthermore, a driving motor whose output end is connected to a corresponding rotating roller is installed on the outer side wall of one of the side plates, and a waste box located at the output port of the metal mesh conveyor belt is placed between the two side plates.

[0012] Furthermore, the water pump is installed on the outer wall of one of the side panels, and a drainage pipe is connected between the output end and the input end of the group nozzle. The two sides of the return water bucket are fixedly installed on the corresponding side panels respectively, and an inlet pipe is connected between the discharge port of the return water bucket and the input end of the water pump.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. Use metal mesh conveyor belt to separate metal scraps and wastewater into solid and water without squeezing, so that the metal scraps will not be broken into smaller particles and fall back into the return water bucket, thus improving the solid-water separation effect;

[0015] 2. The collected waste water is pumped by a water pump and transported to the group nozzle through a drainage pipe. The group nozzle sprays water and uses a brush to clean the metal scraps on the work surface. This can improve the cleaning effect and reduce the possibility of metal scraps remaining on the brush, ensuring the normal operation of the brush. In addition, since the metal mesh conveyor belt is set at one end of the workbench, there will be no problem of metal scraps being unable to be discharged due to large particles, further improving the cleaning effect.

[0026] Example 2

[0027] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the workbench 1 is tilted to facilitate the discharge of wastewater and debris, and two servo motors 11 are installed at one end. The output ends of the servo motors 11 are installed with screws 12 rotatably installed on the workbench 1 surface. The outer rod walls of the screws 12 are threaded with nut seats 13, and connecting seats 14 are installed between the nut seats 13. The brush 15 is lifted and slidably inserted on the connecting seat 14, and the bottom is in contact with the workbench 1 surface, so the brush 15 can be easily disassembled and replaced. The bottom of the workbench 1 is installed with a base 16. The filtering assembly includes two side panels 2 arranged at the lower end of the workbench 1, which are flush with the bottom of the base 16. Two rotating rollers 21 are rotatably installed between the two side panels 2, and a metal mesh conveyor belt 22 The outer roller wall is wrapped around the two rotating rollers 21, and a driving motor 23 connected to the corresponding rotating roller 21 at the output end is installed on the outer side wall of one of the side plates 2. A waste box 24 located at the output port of the metal mesh conveyor belt 22 is also placed between the two side plates 2. As the metal mesh conveyor belt 22 moves around, the metal scraps falling on the surface of the metal mesh conveyor belt 22 will fall from the surface of the metal mesh conveyor belt 22 into the waste box 24 due to gravity and the centrifugal force generated when the metal mesh conveyor belt 22 rotates. The water pump 3 is installed on the outer side wall of one of the side plates 2, and a drain pipe 31 is connected between the output end and the input end of the group nozzle 32. The two sides of the return water bucket 33 are fixedly installed on the corresponding side plates 2, and an inlet pipe 34 is connected between the discharge port of the return water bucket 33 and the input end of the water pump 3.

[0028] The remaining structures are the same as those of Example 1.

[0029] The workflow of this utility model is as follows:

[0030] First, two servo motors 11 are started to drive the corresponding screw rods 12 to rotate, thereby driving the corresponding nut seats 13 to move linearly back and forth along the axial direction of the corresponding screw rods 12, thereby driving the connecting seat 14 and the brush 15 inserted on the connecting seat 14 and the bottom of which is in contact with the surface of the workbench 1 to move synchronously, so as to clean the metal debris remaining on the surface of the workbench 1;

[0031] Secondly, the water pump 3 is started, and the water in the return water bucket 33 is pumped out through the water inlet pipe 34, and water is supplied to the group nozzle 32 through the drainage pipe 31. The group nozzle 32 sprays water on the surface of the workbench 1, and cooperates with the brush 15 to improve the cleaning effect of the metal debris, and at the same time, it can reduce the possibility of the metal debris remaining in the brush 15. Finally, the metal debris is discharged from the lower end of the workbench 1 along with the wastewater and falls on the metal mesh conveyor belt 22;

[0032] Finally, the drive motor 23 is started to drive the corresponding rotating roller 21 to rotate, and then drive the metal mesh conveyor belt 22 to move in a circular motion, so that the metal debris filtered and intercepted by the metal mesh conveyor belt 22 is evenly conveyed to the output port of the metal mesh conveyor belt 22, and finally falls into the waste bin 24, and the wastewater will pass through the mesh of the metal mesh conveyor belt 22, fall into the return water bucket 33, and participate in the wastewater circulation system.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
